How do I update my Nokia-930 to Latest Windows-10 preview?

My 930 currently has OS 10.0.12562.84. I'm set up with Fast Track via Windows Insider.
The phone won't update, but I believe it should have updated at least once, if not more.

The phone is unlocked, purchased from Amazon US. When I performed a reset the language came up as some Asian script that I don't recognize. I don't know whether this would affect things, but it's all that I can image.

Any suggestions on how to achieve the update would be appreciated. The current version is worthless, not installing apps such as Evernote.
